What could it be?? P1456 code

[tonyhatchetman]

I was driving along and it just through that code why what could be causing it?

An easy fix possibility is a lost gas cap or a bad seal in the gas cap.

That's what I was thinking to ....what fuse is it that resets the ecu?

And also would that happen after I used a 1/2 tank of gas ...just all the sudden lose a seal? Thanks
